2-Chloro-N-(2-chloroethyl)acetamide (CAS 13627-28-6) has a molecular formula of C?H?Cl?NO and a molecular weight of 156.01 g/mol, with a chloro group on the acetamide??s methylene and another on the ethyl chain of the amide nitrogen. As a dichlorinated amide intermediate, it is used in synthesizing pharmaceuticals and agrochemicals via nucleophilic substitution reactions. It requires sealed, cool, dry storage to avoid hydrolysis of the amide group, and handling with caution due to its halogenated structure, ensuring stability and safe use in synthetic processes.
